Textured Knurl Pineapple Embedded Nut is a professional embedded fastening fastener specially designed for plastic injection molding and hardware embedding assembly. Featuring a unique pineapple pattern knurled outer surface, this insert nut delivers excellent anti-slip and anti-loosening performance after being embedded in plastic materials. With precise internal thread structure and standardized overall dimensions, the nut can be firmly fixed inside plastic parts, effectively solving the problems of thread slipping, nut loosening and falling off during product use. It is widely applicable for electronic shells, plastic accessories, household appliances and precision plastic molding products.
Core Features
Unique Pineapple Knurl Anti-Slip Design
The outer wall adopts exquisite pineapple flower textured knurling process with uniform and three-dimensional texture. Compared with ordinary straight knurled nuts, the pineapple pattern structure provides larger friction and embedding binding force. After hot melting and embedding, it can closely combine with plastic materials, effectively preventing rotation and displacement, achieving permanent anti-slip and anti-loosening effect.
Precision Thread & Smooth Meshing
The internal thread is processed by precision rolling and tapping technology, with neat tooth shape, uniform pitch and smooth inner wall without burrs. It can be perfectly matched with standard screws, ensuring smooth locking and disassembly. The thread has strong wear resistance, not easy to slip or slide teeth after repeated assembly and use.
High Embedding Stability & Firmness
This insert nut is suitable for hot melt embedding and injection molding integrated molding. The special textured outer structure enables the nut to be tightly wrapped by plastic raw materials during molding. It features high pulling resistance and torsion resistance, will not loosen or separate from plastic parts under normal stress, greatly improving the overall assembly stability of plastic products.
Durable Material Performance
Made of high-quality carbon steel or brass materials as optional, the nut has high hardness, good toughness and strong oxidation resistance. It is not easy to deform during high-temperature embedding processing, and maintains stable structural performance in long-term daily use, with long service life and high cost performance.
